DSA-2549-1 devscripts -- multiple vulnerabilities

Multiple vulnerabilities have been discovered in devscripts, a set of
scripts to make the life of a Debian Package maintainer easier.
The following Common Vulnerabilities and Exposures project ids have
been assigned to identify them:

Raphael Geissert discovered that dscverify does not perform
sufficient validation and does not properly escape arguments to
external commands, allowing a remote attacker (as when dscverify is
used by dget) to execute arbitrary code.

Raphael Geissert discovered that dget does not properly escape
arguments to external commands when processing .dsc and .changes
files, allowing an attacker to execute arbitrary code.
This issue is limited with the fix for CVE-2012-2241, and had
already been fixed in version 2.10.73 due to changes to the code,
without considering its security implications.
